Technical Field

[0001] This utility model belongs to the field of heating furnace technology, and in particular relates to a flameless combustion heating furnace. Background Technology

[0002] In the metallurgical industry, a heating furnace is a device (industrial furnace) that heats materials or workpieces (usually metals) to the rolling or forging temperature. Heating furnaces are used in many industries such as petroleum, chemical, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, and pharmaceuticals.

[0003] Existing heating furnaces often generate a large amount of waste gas during use. If the waste gas cannot be properly eliminated or stored, it can easily have an impact on environmental protection. Therefore, we have specially designed a flameless combustion heating furnace.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0039] Example 1:

[0040] This embodiment provides a flameless combustion heating furnace, characterized in that it includes:

[0041] Combustion section 1;

[0042] Heating section 2;

[0043] Control device 3 is provided on one side of combustion section 1 and heating section 2 is connected to the upper side of combustion section 1;

[0044] The heating part 2 includes:

[0045] Heating box 21, heating box 21 is provided with a heating chamber, and heating box 21 is provided with a cover 24;

[0047] The heating device is located at the bottom of the heating chamber and heats the heating medium.

[0048] As can be seen from this embodiment, a flameless combustion heating furnace includes a combustion section 1, a heating section 2, and a control device 3;

[0049] The control device 3 movably connects the combustion section 1 and the heating section 2 together. In use, the heating section 2 can be separated from the combustion section 1 by the control device 3, which facilitates loading and unloading and makes it easier to use.

[0050] The heating section 2 includes a heating box 21, a guide pipe 22, and a heating device;

[0051] The heating box 21 has an open heating chamber formed inside, and a cover 24 is connected to the upper side of the heating chamber. The cover 24 seals the heating chamber after it is fitted with the heating box 21.

[0052] The guide tube 22 is made of aluminum alloy, which has good thermal conductivity. In the use chamber, the guide tube 22 is installed in a spiral shape in the heating chamber. The spiral arrangement of the guide tube 22 helps to prolong the gas passage time, thereby enhancing the heating effect. The inlet end of the guide tube 22 passes through the cover 24 and extends to the outside of the heating chamber to connect with the external gas supply device. The outlet end of the guide tube 22 passes through the bottom surface of the heating chamber and supplies gas to the combustion section 1 after the heating box 21 is engaged with the combustion section 1.

[0053] By filling the heating chamber with a heating medium, the guide pipe 22 is heated through heat transfer. The guide pipe 22 is spirally arranged, which effectively extends the gas flow path and improves the heating effect. This allows the gaseous fuel to be at a suitable temperature, enabling flameless combustion of the gas, which helps to reduce the emission of carbon dioxide and nitrogen oxides and reduce combustion noise.
